Edge Encryption log file edgeencryption.log periodically shows error: "ERROR Received error in response for keep-alive request. Please check the connectivity between the Edge proxy and the ServiceNow instance. Result : java.util.concurrent.TimeoutException: Total timeout elapsed"



Issue


The Edge Encryption log file edgeencryption.log periodically shows the following error: "ERROR Received error in response for keep-alive request. Please check the connectivity between the Edge proxy and the ServiceNow instance. Result : java.util.concurrent.TimeoutException: Total timeout elapsed"

Solution


  1. Add the following property to each Edge Encryption proxy's /conf/edgeencryption.properties file:

    edgeencryption.proxy.keepalive.interval=11 

  2. Save the file and restart the proxies.

    Setting the keepalive interval from the default of 5 seconds to 11 seconds should help with eliminating this error. Should the error continue, change the interval to a higher prime number, such as 23, 47, ... until the error no longer occurs.

    Increasing this value gives the instance more time to reply to the proxy's "keep alive" request. A delay in response can happen if the instance is busy and the five-second default time is exceeded.
